Here is a simple, Jain-centered answer.

• Five Merus (Panch Meru)

- In the middle world (Madhya Loka), Dhaei Dweep is said to host five Meru mountains: - Sudarshan Meru (Sumeru) in the center of Jambudvipa - Vijay Meru in the middle of the East Dhatkikhand - Achal Meru in the middle of the West Dhatkikhand - Mandar Meru in the middle of the East Pushkarardh - Vidyunmali Meru in the middle of the West Pushkarardh - These five Meru together form the Panchmeru arrangement that structures the central cosmography described in Jain texts. The central Meru is the focal axis, with the others marking the centers of surrounding regions. There can be slight variation in names across texts, but the core idea remains the same across Digambar and Śvetāmbara traditions. You can read more here and here .

• About a map

- Jain cosmology is often depicted as a circular map around Jambudvipa with Mount Meru at the center and concentric continents and oceans. You can explore Jain cosmology maps and Jambudweep models on JainKnowledge pages that describe Jambudweep, Meru, and the global layout. You can read a concise guide to Jain geography here , and see a detailed Jambudweep/Jain cosmology mapping discussion here .
